CO2 can sharpen extreme weather without higher temps
Global efforts to tackle climate change rest on a common goal: to keep the planet's temperatures from rising beyond dangerous thresholds. But what if the gases that come from cars and power plants are harming the planet themselves, even without the warming they cause?
Move over, land use: Climate could hurt animals more
Climate change is on track to become the world's greatest threat to biodiversity in the next half-century, topping human land-use change as the main driver of species loss among vertebrate land animals, new research suggests.
Ambitious climate target is 2 decades away
World leaders have about two decades before overshooting their most ambitious climate goal of preventing temperatures from rising more than 1.5 degrees Celsius. It doesn't sound like much time to turn things around, but it's substantially more wiggle room than some previous estimates have suggested.
Carbon in, methane out: Studies question climate potential
Wetlands are some of the most carbon-rich ecosystems on Earth — and preserving or restoring them, some experts say, can sequester carbon dioxide and help mitigate climate change. It's a strategy known as "blue carbon."
Ice is melting 3 times as fast as it did 25 years ago
The Antarctic ice sheet lost a whopping 3 trillion tons of ice between 1992 and 2017, scientists announced this week.
